A matric pupil who allegedly killed a fellow schoolboy with a sword will appear in the Krugersdorp Magistrate’s Court on Friday.

At his last court appearance on September 26, the court extended Morne Harmse’s period of psychiatric evaluation from 30 to 60 days.

Harmse, brandishing a Samurai sword and wearing a mask, allegedly killed Jacques Pretorius, 16, at the Nic Diederichs Technical High School on August 18. He also allegedly stabbed and injured another boy and two gardeners.

He has told a psychiatrist he had seen a ghost in a field on a farm his parents rented, which instructed him to become a Satanist.
